Embodiment 1

[0035] A sunscreen composition containing indigo extract, comprising the following raw materials in mass percentage:

[0036] Indigo extract 45%; Yerba mate extract 38%; Mignonette extract 15%; Polyol additive 2%.

[0037] Preferably: the polyol additive is a mixture of phenoxyethanol, ethylhexylglycerin, caprylyl glycol, and 1,2 pentanediol in weight ratio, and the mixing ratio is 1:1:1:6.

[0038] The preparation method of the sunscreen composition of the present embodiment comprises the following steps:

[0039] After pulverizing the indigo leaves, add an alkane solvent twice the weight of the indigo leaves to extract for 1 hour, discard the extraction layer, and repeat once. The extracted indigo leaves were added with pure water 8 times the weight of indigo leaves for routine extraction for 3 hours, repeated once, the extract was passed through a 0.5 μm microfiltration membrane, and the permeate was concentrated to obtain indigo extract.

[0040] After pulverizing the Ye...

Embodiment 2

[0044] A sunscreen composition containing indigo extract, comprising the following raw materials in mass percentage:

[0045] Indigo extract 52%; Yerba mate extract 30%; Mignonette extract 15%; Polyol additive 3%.

[0046] Preferably: the polyol additive is a mixture of phenoxyethanol, ethylhexylglycerin, caprylyl glycol, and 1,2 pentanediol in weight ratio, and the mixing ratio is: 1:2:1:8.

[0047] The preparation method of the sunscreen composition of the present embodiment comprises the following steps:

[0048]Crush the indigo leaves and add an alkane solvent 3 times the weight of the indigo leaves to extract for 1 hour, discard the extraction layer, and repeat once. The extracted indigo leaves were added with 30% aqueous ethanol solution 6 times the weight of indigo leaves for conventional extraction for 3 hours, repeated once, the extract was passed through a 0.5 μm microfiltration membrane, and the permeate was concentrated to obtain indigo extract.

[0049] After pu...

Abstract

The invention relates to a sun-screen composition, a preparation method and a sun-screen cosmetic. The sun-screen composition consists of the following components in percentage by weight: 40-55% of an indigofera tinctoria extract, 30-45% of a Paraguay tea extract, 10-25% of a mignonette extract and 1-5% of polyol additives. According to the sun-screen composition disclosed by the invention, various natural plants are scientifically combined on the basis of sun-screen functional characteristics, so that the obtained sun-screen composition is quite strong in UVB and UVA ultraviolet shielding capacity; and the sun-screen composition can protect skin from getting aged, relieve the generation of melanin and repair sunburned skin. The plant raw materials are safe and easily available; and the preparation method is simple in process and is widely applicable to the preparation of sun-screen skin care products.

Description

technical field [0001] The invention relates to the field of cosmetics, and more specifically relates to a sunscreen composition, a preparation method and a sunscreen cosmetic. Background technique [0002] Appropriate amount of ultraviolet radiation can disinfect and sterilize, provide vitamin D needed by the human body, enhance resistance, promote metabolism, and is very beneficial to the development and health of the human body. However, excessive ultraviolet radiation will cause damage to the skin. Direct exposure of ultraviolet rays to the skin can cause a series of skin problems such as skin erythema, burns, blackening, dermatitis and even skin cancer. With the continuous improvement of people's living standards and deeper awareness of health, outdoor sports such as hiking, jogging, and cycling have become indispensable outdoor sports for wage earners. At this time, it is easy to be exposed to ultraviolet rays, which will cause a series of skin problems. Therefore, s...
